• Always wear approved protective glasses or a full visor when assembling or driving.
• Always wear gloves when handling the blades.
• Never wear loose clothing that can get caught in moving parts.
• Use ear protectors to avoid damage to hearing.

Slope Operation

Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

Do not drive up or down hills with slopes greater than 10 degrees. And do not drive across any slopes.

• Mow up and down slopes (10 degrees maximum), not across.
  
• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
• Choose a low ground speed so that you will not have to stop while on the slope.
• Do not mow on wet grass. Tires may lose traction.
• Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blades and proceed slowly straight down the slope.
• Keep movement on the slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause machine to roll over.
• Use extra care while operating machine with grass catchers or other attachments; they can affect the stability of the machine.
• Do not use on steep slopes.
  
• Do not try to stabilize the machine by putting a foot on the ground.
• Do not mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel is over the edge or if the edge caves in.

CHILDREN CAN BE INJURED BY THIS EQUIPMENT. The American Academy of Pediatrics recommends that children be a minimum of 16 years of age before operating a riding lawn mower. Keep children out of the mowing area and in the watchful care of a responsible adult other than the operator.

Children
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

• Keep children out of the mowing area and in the watchful care of a responsible adult other than the operator.
  
• Be alert and turn machine off if a child enters the area.
• Before and while backing, look behind and down for small children.
• Never carry children, even with the blades shut off. They may fall off and be seriously injured or interfere with safe machine operation. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the machine.
• Never allow children to operate the machine.
  
• Use extra care when approaching blind corners, shrubs, trees, or other objects that may block your view of a child.

Safe Handling of Gasoline

The engine and the exhaust system become very hot during operation.
There is risk for burns if touched.
Allow engine and exhaust system to cool before refueling.

To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

• Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
• Use only approved gasoline containers.
• Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling.
• Never fuel the machine indoors.
  
• Never store the machine or fuel container where there is an open flame, spark, or pilot light such as on a water heater or other appliance.
• Before you begin refueling, minimize the risk of static electricity by touching a metal surface.
• Never fill containers inside a vehicle or on a truck or trailer bed with plastic liner. Always place containers on the ground away from the vehicle when filling.
• Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.
• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
• If fuel is spilled on clothing, change clothing immediately.
• Never overfill fuel tank. Replace gas cap and tighten securely.
• Do not start the engine near spilled fuel.
• Never use gasoline as a cleaning agent.
• If leaks arise in fuel system, engine must not be started until problem has been resolved.
• Check the fuel level before each use and leave space for the fuel to expand, as the heat from the engine and the sun may otherwise cause the fuel to expand and overflow.

The engine must not be started when the driver's floor plate or any protective plate for the mower deck's drive belt is removed.

General Maintenance

• Never operate machine in a closed area.
• Keep all nuts and bolts tight to be sure the equipment is in safe working condition.
• Never tamper with safety devices. Check their proper operation regularly.
• Keep machine free of grass, leaves, or other debris buildup. Clean oil or fuel spillage and remove any fuel-soaked debris. Allow machine to cool before storing.
• If you strike a foreign object, stop and inspect the machine. Repair, if necessary, before restarting.
• Never make any adjustments or repairs with the engine running.
• Check grass catcher components and the discharge guard frequently and replace with manufacturer's recommended parts, when necessary.
• Mower blades are sharp. Wrap the blade or wear gloves, and use extra caution when servicing them.
• Check brake operation frequently. Adjust and service as required.
• Maintain or replace safety and instruction labels, as necessary.
• Do not modify safety equipment. Check regularly to be sure it works properly. The machine must not be driven with defective or unmounted protective plates, protective cowlings, safety switches, or other protective devices.
• Do not change the settings of governors and avoid running the engine with overly high engine speeds. If you run the engine too fast, you risk damaging the machine components.
• 
  Be very careful when handling battery acid. Acid on skin can cause serious corrosive burns. If you spill battery acid on your skin, rinse immediately with water.
• Acid in the eyes can cause blindness, contact a doctor immediately.
• Be careful when servicing the battery. Explosive gases form in the battery. Never perform maintenance on the battery when smoking or near open flames or sparks.
  
• The battery can explode and cause serious injury or damage.
• Make sure that the equipment is in good condition and that all nuts and bolts, especially those fastening the blade attachments, are properly tightened and torqued.

Use protective glasses for maintenance work

The battery contains lead and lead compounds, chemicals that are considered to cause cancer, birth defects, and other reproductive system damage. Wash your hands after handling the battery

Sparking can occur when working with the battery and the heavy cables of the starter circuit. This can cause battery explosion, fire or eye injury. Sparking in this circuit can not occur after the chassis cable (normally negative, black) is removed from the battery.

Avoid electrical sparking and its consequences by the following routines:

• Use protective goggles.
• Ensure that the fuel filler cap is mounted tightly and no flammable substances are stored in an open vessel.
• Never work with the starter circuit if there is spilled fuel.
• Disconnect the chassis cable from the battery first and reconnect it last.
• Do not make a bridge short circuit across the starter relay to run the starter.
• Never use the machine indoors or in spaces lacking proper ventilation. The exhaust fumes contain carbon monoxide, an odorless, poisonous, and lethal gas.
  
• Stop to inspect the equipment if you run over or into anything. If necessary, make repairs before starting.
• Never make adjustments with the engine running.
• The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer. Only use approved repair parts for the machine.
• The blades are sharp and can cause cuts and gashes. Wrap the blades or use protective gloves when handling them.
• Check the parking brake's functionality regularly. Adjust and service as necessary.
• The mulch blades should only be used in familiar areas when higher quality mowing is desired.
• Reduce the risk of fire by removing grass, leaves, and other debris that may have accumulated on the machine.
• Allow the machine to cool before putting it in storage.
• Regularly clean deck and underside of deck, avoid spraying engine and electrical components with water.

CONTROLS

This operator manual describes the Husqvarna Zero Turn Rider. The rider is fitted with a Kawasaki four-stroke overhead valve engine.
Transmission from the engine is made via a belt- driven hydraulic pumps. Using the left and right steering controls, the flow is regulated and thereby the direction and speed.

Control Locations

1. Steering control levers
2. Parking brake
3. Tracking adjustment
4. Fuel shut off valve
5. Bypass Linkages
6. Fuel tank
7. Fuses
8. Seat adjustment lever
9. Blade switch
10. Ignition switch

Steering Control Levers

The machine's speed and direction are continuously variable using the two steering controls. The steering controls can be moved forward or backward about a neutral position. Furthermore, there is a neutral position, which is locked if the steering controls are moved outward.
When both controls are in the neutral position (N), the machine stands still.
By moving both controls an equal amount forward or backward, the machine moves in a straight line forward or backward respectively.
For example, to turn right while moving forward, move the right control towards the neutral position. The rotation of the right wheel is reduced and the machine turns to the right.
Zero turn can be achieved by moving one control backward (behind the neutral position) and carefully moving the other steering control forward from its neutral position. The rotation direction when zero turning is determined by which steering control is moved backward behind the neutral position. If the left steering control is pulled backward, the machine turns to the left. Use extra care when using this maneuver.
If the steering controls are in uneven positions when standing still or do not fit in the slots for moving the controls outward, they can be adjusted.

4. Reverse

The machine can turn very rapidly if one steering control is moved much further forward than the other.

Parking Brake

The machine must be not be moving when engaging the parking brake. Always set the parking brake before dismounting. Release the parking brake before moving the mower.

The parking brake is found on the left of the machine. Push the release button and pull the lever backward to activate the brake—push forward to release it.

Throttle Control

The throttle control regulates the engine speed and the rate of rotation of the blades, assuming the blade switch is pulled out,
To increase or decrease the engine speed, the control is moved forward or back respectively.
Avoid idling the engine for long periods, as there is a risk of fouling the spark plugs.
USE FULL THROTTLE WHEN MOWING, for best mower performance and battery charging.

Blade Switch

To engage the mower deck, pull the blade switch knob out. The mower blades are disengaged when the knob is pressed down fully.

Ignition Switch

The ignition switch is placed on the control panel and is used to start and stop the engine.
On models equipped with headlights, turn the key clockwise to ACCESSORY for headlight use.

Choke Control

The choke control is used for cold starts to provide the engine with a richer fuel mixture.
For cold starts on models with separate choke, the control should be pulled up.

Hour Meter

The hour meter displays the total operating time with the blade activated.
The display on the hour meter will turn on the oil can icon after every fifty hours of use and will stay on for two hours or until the meter is manually reset. To manually reset the timer, turn the ignition key to the run position and then engage and disengage the blade switch five times at one second intervals.

Seat Adjustment Lever

The seat can be adjusted lengthways. When making adjustments, the lever under the right side of the seat is pulled up, after which the seat can be moved backward or forward.

Seat should not be adjusted while unit is in motion.

Fuse

The 20 amp primary fuse is located on the left hand side of the machine. It is accessed by tilting the seat forward. The fuse is a flat pin type used in automobiles.

Tracking Knob

If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 15 psi (103 kPa / 1 bar) for all tires. Tracking must be checked on a flat and level concrete or blacktop surface.
Rotating the tracking knob allows fine tuning adjustments so the machine tracks straight with the steering control levers in the full forward position.
Rotate the knob counter clockwise (as viewed from the operation position) to increase the speed on the left lever. Rotate clockwise to decrease speed.

Fuel Tank

Read the safety instructions before refueling. The machine has one fuel tank, just behind the console. The tank capacity is 3.5 gallons (13.25 liters).

Regularly check the gas cap gasket for damage and keep the cap properly tightened.

The engine will run on a minimum of 85-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used. See also Technical Data concerning ethanol fuel. Methanol fuel is not allowed. Do not use E85 alcohol based fuel. Damage to engine and components may occur.
When operating in temperatures below 32°F. (0°C.), use fresh, clean winter grade gasoline to insure good cold weather starting.

Gasoline is highly flammable. Observe caution and fill the tank outdoors (see the safety instruction).

The engine and the exhaust system, become very hot during operation.
Risk for burns if touched.
Allow engine and exhaust system to cool before refueling.

Fill to bottom of filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.

Experience indicates that alcohol blended fuels (called gasohol, ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage Instructions for additional information. Never use engine or carburetor cleaners in the fuel tank or permanent damage may occur.

Fuel Shut Off Valve

The fuel shut off valve is located at the left rear of the seat. The valve is off when the handle tab is turned perpendicular to the fuel line.

Always raise the deck to the highest position for transport.

Cutting Height Adjuster

To set the desired deck cutting height, press the release button and move the lever forward to the preset height pin and release the button. See Before Starting in the Operation section to change the cutting height. The cutting height range is from 1½" (38mm) to 4" (102mm) in ½" (13mm) increments. The heights are measured from the ground up to the blade tip with the engine not running.

To obtain an even cutting height, it is important that the air pressure in all tires is 15 psi / 103 kPa / 1 bar.

Bypass Linkages

The levers are located on each side of the rear of the unit below the rear engine plate. The bypass linkage is used when manually pushing or pulling the unit. See Moving Machine By Hand in the Operation section.

Bypass linkages are located close to the muffler. To prevent burns, the engine should be shut off and allowed to cool before the bypass linkage levers are handled.

OPERATION

Training

Due to unique steering capabilities, zero turn mowers are far more maneuverable than typical riding mowers.
This section should be reviewed in its entirety prior to attempting to move the mower under its own power. When first operating the mower or until becoming comfortable with controls, use a reduced throttle speed and reduced ground speed. DO NOT move control levers to the furthest forward or reverse positions during initial operation.
First time users should become familiar with the mower's movement on a hard surface, such as concrete or blacktop PRIOR to attempting to operate on turf. Until the operator becomes comfortable with the mower controls and zero turning capability, overly aggressive maneuvers may damage turf.

Steering

To move forward and backward
The direction and speed of the mower's movements are effected by the movement of the control lever(s) on each side of mower. The left control lever controls the left wheel. The right control lever controls the right wheel.
First time users should push the mower (see Moving Machine By Hand in the Operation section) to an open, flat area without other people, vehicles or obstacles nearby. To move the unit under its own power, the operator must sit in the seat and start the engine (see Before Starting in the Operation section). Adjust the engine speed to idle, disengage the parking brake but do not engage the blades at this time. Rotate control levers inward. As long as the control levers have not been moved forward or backwards, the mower will not move.
Slowly move both control levers forward slightly. This will allow mower to start moving forward in a straight line. Pull the control levers back to the neutral position and the mower should stop moving.
Pull back slightly on control levers, allowing the mower to move backwards. Push the control levers forward to the neutral position and mower should stop moving.

To turn to the right
While moving in a forward direction, pull the right lever back towards the neutral position while maintaining the position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in that direction.

To turn to the left
While moving in a forward direction pull the left lever back towards the neutral position while maintaining the position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in that direction.

To zero turn
While moving in a forward direction, first pull both control levers back until the mower stops or slows dramatically.
Then by alternating one lever slightly to the forward position and the other in the reverse position, complete the turn.

Before Starting

1. Read the sections on Safety and Controls before starting the machine.
2. Perform the daily maintenance before starting (see Maintenance Schedule in the Maintenance section).
3. Check that there is sufficient fuel in the fuel tank.
4. Adjust the seat to the desired position.
   
5. Set the deck cutting height by inserting the lift pin into the desired cut height. Resecure the lift pin with the hairpin.
   

The following conditions must be fulfilled before the engine can be started:

• The blade switch must be pressed downward into the disengaged position.
• The parking brake must be up into the activated position.
• Both steering controls must be in the locked (outer) neutral position.

Starting the Engine

1. Sit on the seat.
2. Raise the mower deck by pushing the release button on the top of the lifting lever. Pull the lifting lever backward to the locked (transport) position.
   
3. Activate the parking brake by pushing the release button in and pulling the lever fully upwards.
   
4. Disengage the mower blades by pressing the blade switch downwards.
   
5. Move the steering controls outward to the locked (outer) neutral position.
   
6. Move the throttle to the middle position.
   
7. If the engine is cold, the choke control should be pulled up.
   
8. Press in and turn the ignition key to the start position.
   

Do not run the starter for more than 5 seconds each time. If the engine does not start, wait approximately 10 seconds before retrying.

9. When the engine starts, immediately release the ignition key back to the run position. Push the choke control in gradually when the engine has started.
   

Engine exhaust and certain vehicle components contain or emit chemicals considered to cause cancer, birth defects or other reproductive system damage. The engine exhaust contains carbon monoxide, which is a odorless, colorless, poisonous gas. Do not use the machine in enclosed spaces.

10. Set the engine speed with the throttle. Allow the engine to run at a moderate speed, approximately mid throttle, for 3-5 minutes before loading it too heavily. USE FULL THROTTLE WHEN MOWING (no choke).
    

Weak Battery

Lead-acid batteries generate explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection when around batteries.

Your mower is equipped with a 12-volt negative grounded system. The other vehicle must also be a 12-volt negative grounded system. Do not use your mower to start other vehicles.

If the battery is too weak to start the engine, it should be recharged. (See Battery in the Maintenance section.)

Jumper Cables Use

1. Connect each end of the RED cable to the POSITIVE (+) terminal on each battery, taking care not to short against chassis.
2. Connect one end of the BLACK cable to the NEGATIVE (-) terminal of the fully charged battery.
3. Connect the other end of the BLACK cable to a good CHASSIS GROUND on the mower with the discharged battery, away from the fuel tank and battery.

To remove cables, reverse order

4. Remove BLACK cable first from chassis and then from the fully charged battery.
5. Remove RED cable last from both batteries.

Running

1. Release the parking brake by pushing the top release button in and moving the lever downward.
   NOTE: The mower is equipped with an operator presence system. When the engine is running, any attempt by the operator to leave the seat without first setting the parking brake will shut off the engine.
   
2. Move the steering controls inwards, out of the neutral position (N).
3. Push the release button on the cutting height lever and move lever to the pin, release the button.
   

Make sure that no one is near mower when engaging blade switch.
Make sure the work area is free from objects that could be thrown by the rotating blades.

4. Move throttle control to full throttle.
5. Engage the mower deck by pulling out the blade switch.

Operating On Hills

Read the Safety Instructions Driving on Slopes in the Safety section.

Do not drive up or down hills with slopes greater than 10 degrees. Do not drive across slopes.

• The slowest speed possible should be used before starting up or down hills.
• Avoid stopping or changing speed on hills.
• If stopping is absolutely necessary, pull steering controls into the neutral position and push to the outside of the unit. Engage the parking brake.
  
• To restart movement, release the parking brake.
  
• Pull the control levers back to the center of the mower and press forward to regain forward motion.
• Make all turns slowly.

Mowing Tips

• Observe and flag rocks and other fixed objects to avoid collisions.
• Begin with a high cutting height and reduce it until the desired mowing result is attained. The average lawn should be cut to 2½" (64 mm) during the cool season and over 3" (76 mm) during the hot months. For healthier and better looking lawns, mow often after moderate growth. For best cutting performance, grass over 6" (15 cm) in height should be mowed twice. Make the first cut relatively high, the second to the desired height.
• The mowing result will be best with a high engine speed (the blades rotate rapidly) and low speed (the rider moves slowly). If the grass is not too long and dense, the driving speed can be increased without negatively affecting the mowing result.
• The finest lawns are obtained by mowing often. The lawn becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher operating speed can be used without poor mowing results.
• Avoid mowing wet lawns. The mowing result is poorer because the wheels sink into the soft lawn, clumps build, and the grass clippings fasten under the cowling.
• Hose the mower deck underside with water after each use. When cleaning, the mower deck shall be raised into the transport position. Make sure the mower is cooled and the engine is off.
• Use compressed air to clean top surface of the deck. Avoid flooding water on top surface, engine and electrical components.
• When the mulching kit is used, it is important that the mowing interval is frequent.

Clear the lawn of stones and other objects that can be thrown out by the blades.

Never drive the rider on terrain that slopes more than 10 degrees. Mow slopes up and down, never side to side. Avoid sudden directional changes.

Stopping the Engine

1. Move the throttle to the minimum position (tortoise symbol).
2. Move the steering controls outward.
3. Disengage the mower deck by pressing the blade switch down.
   
4. Raise the mower deck by pressing the release button on the lever and pulling the lever upward to the transport position.
   
5. When the machine is standing still, activate the parking brake by pushing the lever release button and pulling the lever upward.
   If the engine has been worked hard, allow it to idle at least 60 seconds to attain a normal operating temperature before stopping. To prevent fouling the spark plugs, avoid idling the engine for longer periods.
6. Turn the ignition key to the stop position.
7. Remove key. Always remove key when leaving the mower to prevent unauthorized use.

Leaving the ignition switch in any other position than OFF will cause the battery to be discharged.

Moving Machine By Hand

When pushing or pulling the mower, engage the EZT bypass linkages. The EZT bypass linkages are located on the rear of the frame, below the rear engine guard.

1. Raise the deck into the highest cutting position.
2. Engage the parking brake.
3. Pull the EZT bypass linkages up and out of the keyhole slots. Release the levers with the head outside the frame and held in the bypass position.
   
4. To reengage the EZT's to drive, reverse the above procedure.
   

Load the machine into truck or trailer by driving slowly up the ramps. DO NOT LIFT! The machine is not intended to be lifted by hand.

Bypass linkages are located close to the muffler. To prevent burns, the engine should be shut off and allowed to cool before the bypass linkage levers are handled.

Make no adjustments without:

• the engine stopped,
• the ignition key removed,
• the parking brake activated

Use extreme caution when loading the machine into a truck or trailer using ramps. There is the possibility of serious injury or death if the machine falls off the ramps.

Always use two wrenches for the terminal screws.

Do not short battery terminals by allowing a wrench or any other object to contact both terminals at the same time. Before connecting battery, remove metal bracelets, wristwatch bands, rings, etc.
Positive terminal must be connected first to prevent sparks from accidental grounding.

Safety System

The machine is equipped with a safety system that prevents starting or driving under the following conditions.
The engine can only be started when:

1. The mower deck is disengaged.
2. The steering controls are in the outer, locked neutral position.
   
3. The parking brake is on.

Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met. Change the conditions and try again.
If the machine starts when one of these conditions is not met, turn the machine off and repair the safety system before using the machine again.
Make sure the engine stops when the park brake is not engaged and the operator leaves the seated position.
Check that the engine stops if the mower blades are engaged and the driver temporarily moves off the drivers seat.

Parking Brake

Visually check that no damage is found on the lever, links or switch belonging to the parking brake. Perform a standstill test and check that there is sufficient braking action.
To adjust the parking brake, contact the Husqvarna service workshop.

The machine must be absolutely standing still when applying the parking brake.

Faulty adjustment will result in reduced braking ability and can cause an accident.

Tire Pressures

All tires should be at 15 psi / 103 kPa / 1 bar.

Anti-scalp Rollers

Adjust anti-scalp rollers with the mower on a flat level surface.

Anti-scalp rollers are properly adjusted when they are just slightly off of the ground when the deck is at the desired cutting height in the operating position. Antiscalp rollers then keep the deck in the proper position to help prevent scalping in most terrain conditions. Anti-scalp rollers can be set in four positions. The rollers should be approximately ¼" (6.5 mm) from ground. Do not adjust the rollers to support the deck.

To avoid deck damage, the anti-scalp rollers must not be adjusted to support the deck.

V-belts

Check every 100 hours of operation. Check for severe cracking and large nicks.
NOTE: The belt will show some small cracks in normal operation.
The belts are not adjustable. Replace belts if they begin to slip from wear.

Removing the deck belt

1. Belt guide
2. Idler arm

Deck Belt Removal

1. Park on a level surface. Apply parking brake.
2. Lower the deck into the lowest cutting position.
3. Remove bolts from belt shields and remove shields.
4. Remove any dirt or grass that may have accumulated around the cutter housings and entire deck surface.
5. Loosen the nut securing the belt guide. Note the position of the belt guide for reinstallation.
6. Push inward on the idler arm to release the tension on the belt.
7. Carefully slip the belt over the top of the cutter housing pulleys and remove belt from the deck.

Deck Belt Installation
NOTE: For ease in installing the deck belt, refer to the routing decal on the top of the deck.

1. Wrap the deck belt around the electric clutch pulley that is located on the engine shaft.
2. Route the belt forward and up onto the deck.
   
3. Place belt around spring loaded idler pulley.
4. Wrap the belt around the stationary idler pulley and around the mandrel housings.
5. Push inward on the idler arm and carefully route belt over stationary idler pulley. Once the belt is properly routed, slowly release the idler arm to tension belt.
6. Double check belt routing to make sure it matches the decal affixed to the deck, and the belt does not have any twist. Correct if needed.
7. Tighten the belt guide and replace belt shields on both mandrel housings and secure with fasteners.
   NOTE: The belt guide should be perpendicular to the belt when installation is complete.

Cutting Blades

To attain the best mowing effect, it is important that blades are well sharpened and not damaged.
Replace blades that have been bent or cracked when hitting obstacles.
Let the service workshop should decide whether the blade can be repaired/ground or must be replaced. Balance the blades after sharpening.
Check the blade mounts.

Blade attachment

1. Blade
2. Blade bolt (special)
3. Spindle housing

Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.
The sharpening of blades should be carried out by an authorized service workshop.

Blade replacement

1. Remove blade bolt by turning counterclockwise.
2. Install new or resharpened blade with stamped GRASS SIDE facing towards ground/grass (down) or THIS SIDE UP facing deck and spindle housing.
3. Seat the blade opening firmly onto the spindle housing.
4. Tighten blade bolt securely.
5. Torque blade bolt to 45-55 ft/lbs (60-75 Nm).

Special blade bolt is heat treated.
Replace with a Husqvarna bolt if required.
Do not use lower grade hardware than specified.

Adjusting the Deck

Leveling deck
Adjust the deck while the mower is on a level surface. Make sure the tires are inflated to the correct pressure. See Technical Data / Transmission. If tires are under or over inflated, the deck cannot be properly adjusted. Raise the deck to the highest (transport) position.
The deck should be adjusted slightly higher in the rear.
NOTE: To insure accuracy of leveling procedure, mower deck drive belt must be installed prior to leveling deck.

1. Wear heavy gloves. Turn each blade tip to align side to side.
   
2. Measure from the floor surface up to the bottom of the blade tip on the discharge side of the mower deck. Record this measurement.
3. Move to the opposite side, check that the measurement is the same. If adjustment is required—with a ¾" or adjustable wrench, turn the lift link adjustment nuts on either side counter clockwise to lower or clockwise to raise. Adjust until both side-to-side measurements are equal.
   
4. Turn either blade to align with the deck in front-to-rear manner. If the front blade tip does not measure ¹/₈" to ½" higher in the rear, follow the front adjustment instructions that follow.
5. With a ⁵/₈ or adjustable wrench, turn the nuts on the front suspension linkage. Clockwise raises the front of the mower, counterclockwise will lower the front. Adjust nuts until rear of mower deck is positioned level to ¹/₈" higher in the rear than the side-to-side measurement.
   NOTE: This will place the mower deck in a standard measurement position. Depending on the type of grass being mowed or environmental conditions, additional adjustments may be required to achieve the desired cut.
   

Caster Wheels

Check every 200 hours. Check that wheels rotate freely. If wheels do not rotate freely take the unit to your dealer for service.
Foam filled tires or solid tires will void the warranty.

Removal and installation of caster wheel

1. Remove nut and caster bolt.
2. Pull the wheel out of the yoke and take care of the spacers.
3. Install in reverse order. Tighten caster bolt.

DO NOT add any type of tire liner or foam fill material to the tires. Excessive loads created by foam filled tires will cause premature failures.
Only use O.E.M. specified tires.

Cleaning

Use protective glasses when cleaning and washing.

Regular cleaning, especially under the mower deck, will increase the machine's life-span. Make it a habit to clean the machine directly after use (after it is cooled), before the debris sticks.

Do not spray water on the top of the mower deck. Use compressed air to clean the top side of mower deck. Regularly clean the underside of the deck with normal water pressure. Do not use a high pressure washer or steam cleaner. Avoid spraying engine and electrical components with water.
For models fitted with a cleanout port, attach the quick connect (from the accessory packet) to any garden hose. After mowing, snap the hose to the cleanout port and turn on water supply.
Restart the mower and engage the blades to use the spinning action to wash away debris. Make sure the hose is away from the mower blades.
Do not rinse hot surfaces with cold water. Let unit cool before washing.

Hardware

Check daily. Inspect the entire machine for loose or missing hardware.

LUBRICATION

Lubrication Schedule

General
Remove the ignition key to prevent unintentional movements during lubrication.
When lubricating with an oil can, it must be filled with engine oil.
When lubricating with grease, unless otherwise stated, use a high grade molybdenum disulphide grease.
For daily use, the machine should be lubricated twice weekly.
Wipe away excess grease after lubrication.
It is important to avoid getting lubricant on the belts or the drive surfaces on the belt pulleys. Should this happen, attempt to clean them with spirits. If the belt continues to slip after cleaning, it must be replaced. Gasoline or other petroleum products must not be used to clean belts.

Use minimal lubrication and remove excess lubricant so that is does not come into contact with belts or belt pulley drive surfaces.

Engine Oil Change

The engine drain plug is located close to the muffler. To prevent burns, the engine should be shut off and allowed to cool slightly so the engine is still warm but the surrounding surfaces and oil are not.

NOTE: Change the engine oil when the engine is warm. Refer to the engine owner's manual for the correct replacement oil and filter change recommendations.

1. Park on a level surface. Apply parking brake.
2. Clean the dirt and debris from the area around the oil fill cap.
3. Remove the cap/dipstick.
4. Locate the drain hose at the left rear of the engine near the bypass linkage. Place an adequately sized container under the end of the drain hose and remove the oil drain plug.
   
5. Allow the oil to fully drain from the engine.
6. Replace the drain hose plug and tighten securely.
7. Fill the engine with new oil to the bottom of the fill tube threads. Check the level with the dipstick.
8. Replace the oil fill cap securely when the oil level is FULL.
9. Refer to the Service Journal for oil checking and changing intervals and change recommendations.

Wheel and Deck Zerks

Use only good quality bearing grease.
Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality.

Front Wheel Mount
Lubricate 3-4 strokes with a grease gun on each set of wheel bearings.

Front Wheel Bearings
Lubricate 3-4 strokes with a grease gun on each set of wheel bearings.

Deck Spindles
Lower the cutting deck completely.
If a grease gun without rubber hose is used, the foot plate must be removed to access the center deck spindle.
Lubricate with a grease gun, 2-3 strokes per spindle.

Transmission

The transmission is maintenance free with no need for level checks or oil changes. If a leak occurs, replace the unit or contact your Husqvarna dealer.

STORAGE

Winter Storage

The machine should be readied for storage at the end of the mowing season or if it will not be in use for longer than 30 days. Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carburetor and disrupt engine function.
Fuel stabilizers are an acceptable option as regards to the sticky residues that can occur during storage.
Add stabilizer to the fuel in the tank or in the storage container. Always use the mixing ratios specified by the manufacturer of the stabilizer. Run the engine for at least 10 minutes after adding the stabilizer so that it reaches the carburetor. Do not empty the fuel tank and the carburetor if you have added stabilizer.

Never store an engine with fuel in the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open flames, sparks, or a pilot light such as in a boiler, hot water tank, clothes dryer, etc. Handle the fuel with care. It is very flammable and can cause serious personal injury and property damage. Drain the fuel into an approved container outdoors and store far away from open flame. Never use gasoline for cleaning. Use a degreaser and warm water instead.

To ready the machine for storage:

1. Thoroughly clean the machine, especially under the mower deck. Touch up damage to the paint and spray a thin layer of oil on the underside of the mower deck to avoid corrosion.
2. Inspect the machine for worn or damaged parts and tighten any nuts or screws that may have become loose.
3. Change the engine oil; dispose of properly.
4. Empty the fuel tanks or add a fuel stabilizer. Start the engine and allow it to run until the carburetor is drained of fuel or the stabilizer has reached the carburetor.
5. Remove the spark plug and pour about a tablespoon of engine oil into the cylinder. Turn over the engine so that the oil is evenly distributed and then refit the spark plug.
6. Lubricate all grease zerks, joints, and axles.
7. Remove the battery. Clean, charge, and store the battery in a cool place, but protect it from direct cold.
8. Store the machine in a clean, dry place and cover it for extra protection.

Service

When ordering spare parts, please specify the purchase year, model, type, and serial number.
Always use genuine Husqvarna spare parts.
An annual check-up at an authorized service workshop is a good way to ensure that your machine performs its best the following season.
